He said: "The doctors told me here are your twins, they are conjoined from the head. I had never seen babies like this and I was nervous.”

Rabia and Rukia spent 15 days in an intensive care unit before their parents were able to take the twins home to meet their older sister.

Taslima said: ‘”After first seeing them Rafia was asking me why are they like this? They don’t look good, why are their heads together? Please separate their heads.

So, I told her that both babies are beautiful. I will take them to Dhaka for an operation to separate their heads; after that you can hold them.”

Doctors are monitoring the twins’ health and assessing if and when surgical separation is possible.

Professor Rohu Rahim, pediatric surgeon from Banghabandhu Sheik Murjib Medical University, who is consulting the family, said: "The babies' heads are joined side by side, in other kids we can see their heads are joined front to back, which creates movement problems.

"As their heads are joined side by side it makes physical movement, such as bending the neck, easier."
